place of the usuall team to take the eiiiciently abovedescribed ,enabling` the tractor andthe farming `iliplement drawn thereby to be operated in closer proximity to .fences and trees and ina head on direction as well as laterally. L

kA further object of the invention fis to provide simple and eective means whereby the machine may besteered and'turned in its and whereby the hitchingpoint of a plow or other farming implement may `be adiusted up and ldown to obtain 'the bestl results., Y

Withthe above and other obiects in view,

the invention consists in the novel construction, combination and arrangement of parts,

as will hereinafter be more fully described,

illustrated and claimed.

In the accompanying 1 is a side elevation of al farm tractor embodying plan view of the' same. Fig. 3 Ais a. vertical cross section taken just in rear of the yoke and lookingin a-forward direction.v Fig. It `is a detail-section through the mechanism of the front steering and traction wheel, showing the driving yand steering mechanism. Fig. 5 is'a detail section on the line 5--5 of Fig. 3. Fig. 6 is a detail section on the line tr-G of Fig. 3.

-'view, Fig. yand 'said side -bars being connected at suitable intervals in rigidlrelation f to each other. These side bars` 3 arearranged as close together as practicable and ordinarily will only be spaced apart asiiiiicient distanceto receive between them the rear traction wheel las clearly shown in Flg. 2, together with any necessarydiiving .elements for imparting. motion toSadrerl driving wheel. l Y Located at one side of the machine frame 1s a lateral stabilizing wheel 4 whichl is moiinted ina. l'fork 5i the stein 6 ,ofwhih Apasses through 'averticalopening in the oiiter end of a yoke 7, the stein 6` being fastened 'by means 'of a clamping nut; 'Siwhich prevents 'the fork 5 from tiirningr- The yoke is connected -at its innerrend 'with the machine rame by means of a universal joint whichA 1s illustratedl as .comprising a head -piece 9 mounted to turn on a vertical. pivot 'ioyextendmg upwardly from the top of a guide 4frame 11 hereinafter f more' particu* larly described, the yoke 7 being directly connected -to the head piece 9 by means of a horizontal pivot 12. This `forms a universal ]oint between the yoke'? and the machine frame which enables said yoke to be swung around so that it may be disposed at either Side of the mainframe ofl the machine to accommodate right and left hand plows and the like.

The guide Aframe 1.1i, as shown in Fig, 3,

is l of open rectangular form comprising parallel vertical side bars 13 which are fastened rigidly t'o the side bars 3 of the Lmachine frame and connected at the bottoinbya cross bar 14. Mounted slidingly on one .of

' the cross bars 13 is a vertically movabie runner 15 to which lis pivotally connected one end of a brace 16 the opposite end Aof which4 is pivotally yoke 7 at a point intermediate the ends of fsaid'yoke as clearlyl shown in Fig. 3. At 4tached to the slidable runner 15 -is'a crank arm 18 on one end of a shaft 19extendin transversely of the mach-ine frame, gsai shaft being provided with another arm 20 from which a connecting rod 21 extends back to a manually controlled lever '22. Thus the operator while inhis seat on the machine may raise and lower the runner 15 and correspondingly vary the angle of the yoke 7 so as to give any desired list to Ithe machine frame and the front and rear Wheels 1 and 2.

connected at 17 to the back to a hand lever 31 within convenient sob reach of the operator. The operator while in his seat on the machine may thus raise and lower 'the clevis 24 and may also adjust the angle of the yoke 7 to vary the lateral inclination of the main frame and also to adapt. the machine to work on hillsides.

The front steering and traction wheel 2 is mounted in a fork 32 which is mounted to turn on a vertical axis for steering purposes. The fork 32 is mountedunder a cylindrical headc33 in which is journaled a shaft 34 concentric with the axis of turning movement of the fork 32, said shaft 34 having fast thereon a bevel gear wheel 35 which is driven by a pinion 36 on the forward section 37 of a central longitudinal shaft which is driven by the shaft 38 of an internal comustion motor conventionally :illustrated at A. The shafts 37 and 38 are connected by a shiftable clutch 39 which is normally held open so that the front Wheel 2 is not driven On the same shaft 34 with the wheel 35 is a spur gear wheel 40 which drives a similar wheel 41 on a countershaft 42 having fast thereon a bevel pinion 43 meshing with a bevel gear wheel 44 on the hub of the front wheel 2` The mechanism just hereinabove described provides for driving the wheel 2 in addition to the wheel 1.

The front wheel is turned for steering purposes by means of a hand controlled wheel 45 on the rear end of a steering shaft 46 connected by a universal joint 47 to another forward section 48 the shaft section 48 being provided with a pinion 49 which meshes with a gear wheel 50 having a fixed relation to the fork 32. The engine shaft is connected by a clutch 51 to a rear shaft section 53 which is in turn geared to a cross shaft 54 from which one or more chains 55 extend around one or more sprocket wheels 56 having a fixed relation to the rear traction wheel 1.

57 designates the gasolene tankv and 58 the driversseat.

From the foregoing description taken in connection with the accompanying drawings it will be seen that I have produced a very simple and cheaply constructed tractor especially adapted for farm purposes in the way above indicated and that by reason of the narrow frame of the machine, the trac- 'universal joint of the same shaft,

tor may be driven laterally or head on iL very close proximity to fences, trees, barns and other obstructions. -It will further be understood that the tractor is adapted equally well to both right and left hand plows and other farming implements by reason of the fact that the lateral stability Wheel may be arranged at either side of the main frame by reason of the reversibility of the yoke 7. Furthermore, the machine is admirably adapted to hillside Work by rea son of the pivotal mounting of the yoke and the adjusting mechanism used in connection therewith.

1. A tractor comprising a single rear traction wheel,'a single front traction and steering wheel in line with said rear wheel, a machine frame embodying parallel side bars arranged in close proximity to the plane lof movement of said wheels and at opposite sides thereof, steering and motor driving .mechanism for said Wheels, a side stabilizsteering wheel in line with said rear wheel,

a machine frame embodying parallel side bars arranged in close proximity to the plane of movement of said wheels and at opposite sides thereof, steering and motor driving mechanism for said wheels, a side stabilizing wheel located outside of said frame, a laterally extending yoke having a connected with the machine frame and terminally supported by said stabilizing Wheel,

and a brace interposed'between said yoke and the machine frame, said yoke being reversible by means of saidvuniversal joint so that it may be disposed at either side of the machine frame.

3. A tractor comprising a singlerear traction wheel, a single front traction and steering wheel in line with said rear wheel, a machine frame embodying parallel side bars arranged in close proximity to the plane of movement of said wheels and at opposite sides thereof, steering and motor driving mechanism for said wheels, a side stabilizing wheel located outside of said frame, a laterally extending yoke having a universal joint connected with the machine frame and terminally supportedby said stabilizing wheel, a brace interposed between s aid yoke and the machine frame, and means under `control of the operator on the machine for to change ing wheel in line with said rear wheel, a

machine frame embodying parallel side bars arranged in close proximity to theplane of ,movement of said wheels andxat opposite sides thereof, steering 'and motor driving mechanism for said wheels, a side stabilizing wheel located outside of said frame, a vertically arranged guide extending downwardly below the machine frame in rear of 10 said front wheel, a clevis slidable up and down on lsaid guide, and means under the control of the driver for raising and lowering said clevis.

In testimony whereof I aiix my Signature in presence of two witnesses.
